Description

本発明は、少なくとも1つの上面および/または底面に装飾を有する木質材料ボードを仕上げ加工するための方法に関する。   The present invention relates to a method for finishing a wood material board having a decoration on at least one top and / or bottom.

このような木質材料ボードは広く普及されており、多くの種々の領域で用いられる。特に大きな使用範囲は、フロアパネルとしての使用である。特にこの使用の場合に、装飾を備えた木質材料ボードは、特に通過による非常な負荷に晒されている。木質材料ボードがこれらの負荷に耐えねばならないためには、装飾層が、保護層によって覆われねばならない。この保護層は、通常、合成樹脂、例えばメラミン樹脂からなる。合成樹脂には、種々の添加剤が混合されている。木質材料ボード上に付着された種々の層によって、木質材料ボードのたわみをもたらすことになる引張り応力が生じる。従って、質材料ボードの上面のみならず底面も被覆されねばならない。その目的は、これらの力を、両面に均等に発生させ、かつ、かくしてたわみを回避させるためである。   Such wood material boards are widely used and used in many different areas. A particularly large range of use is the use as a floor panel. Especially in this use, the wood material board with decoration is exposed to a very heavy load, especially due to passage. In order for the wood board to withstand these loads, the decorative layer must be covered by a protective layer. This protective layer is usually made of a synthetic resin, such as a melamine resin. Various additives are mixed in the synthetic resin. The various layers deposited on the wood material board create tensile stresses that will cause the wood material board to deflect. Therefore, not only the top surface of the quality material board but also the bottom surface must be covered. The purpose is to generate these forces equally on both sides and thus avoid deflection.

木質材料ボードへの合成樹脂層の塗布は、多様な方法でなされることができる。例えば、粒質または粉末としての合成樹脂を、木質材料ボードの、被覆される面に付着させ、かつ、必要な場合には、準備された添加剤を散布することは、知られている。圧力および温度の影響下での最終的な圧縮の最中に、塗布された粉末が溶けて、均一な層を形成する。この方法では、木質材料ボードの両面被覆は、当然ながら、不可能である。何故ならば、上に撒かれた粉末は、木質材料ボードの上面のみにあって、圧縮中にはじめて、上面と結合されるからである。   The synthetic resin layer can be applied to the wood material board by various methods. For example, it is known to attach a synthetic resin as a granulate or powder to the surface of a wood material board to be coated and, if necessary, spray the prepared additive. During the final compression under the influence of pressure and temperature, the applied powder melts to form a uniform layer. In this way, it is of course impossible to cover both sides of a wooden material board. This is because the powder sown above is only on the top surface of the wood material board and is only bonded to the top surface during compression.

特許文献1からは、メラミン樹脂からなる保護層を、木質材料ボードの上面の装飾へ付着させることは公知である。同時に、木質材料ボードの底面に、同様に、メラミン樹脂からなる保護層を付着させることが意図されている。この場合、付着された樹脂層は、圧縮中に、溶け、かくして、装飾を閉じ込めることが意図される。   From Patent Document 1, it is known to attach a protective layer made of melamine resin to the decoration on the upper surface of a wooden material board. At the same time, it is intended to adhere a protective layer made of melamine resin to the bottom of the wood material board as well. In this case, the deposited resin layer is intended to melt during compression, thus confining the decoration.

特許文献2では、液状樹脂の使用が記載されている。この液状樹脂は、木質材料ボードの上面および底面に付着される。   Patent Document 2 describes the use of a liquid resin. This liquid resin is attached to the upper surface and the bottom surface of the wood material board.

この課題の提示を出発点として、木質材料ボードを仕上げ加工するための上記の方法を改善することが意図される。   Starting from the presentation of this task, it is intended to improve the above method for finishing wood material boards.

上記課題の解決は、以下の段階を、すなわち、
(a)木質材料ボードの上面および底面を洗浄すること、
(b)コランダム粒子を含む第1の上方の樹脂層を木質材料ボードの上面に、第1の下方の樹脂層を底面に付着させること、
(c)第1の上方の樹脂層および第1の下方の樹脂層を3%ないし6%の残留含水率に乾燥させること、
(d)セルロースを含む第2の上方の樹脂層を木質材料ボードの上面に、および第2の下方の樹脂層を底面に付着させること、
(e)第2の上方の樹脂層および第2の下方の樹脂層を3%ないし6%の残留含水率に乾燥させること、
(f)ガラス粒子を含む少なくとも第3の上方の樹脂層を木質材料ボードの上面に、および少なくとも第3の下方の樹脂層を底面に付着させること、
(g)前記第3の上方の樹脂層および第3の下方の樹脂層を3%ないし6%の残留含水率に乾燥させること、および
(h)多層構造を圧力の影響および温度の影響下で圧縮すること、を有する、本発明に係わる方法によって、改善することが意図される。
The solution to the above problem involves the following steps:
(A) cleaning the top and bottom surfaces of the wood material board;
(B) attaching a first upper resin layer containing corundum particles to the top surface of the wood material board and a first lower resin layer to the bottom surface;
(C) drying the first upper resin layer and the first lower resin layer to a residual moisture content of 3% to 6%;
(D) attaching a second upper resin layer containing cellulose to the top surface of the wood material board and a second lower resin layer to the bottom surface;
(E) drying the second upper resin layer and the second lower resin layer to a residual moisture content of 3% to 6%;
(F) attaching at least a third upper resin layer containing glass particles to the top surface of the wood material board and at least a third lower resin layer to the bottom surface;
(G) drying the third upper resin layer and the third lower resin layer to a residual moisture content of 3% to 6%; and (h) the multilayer structure under pressure and temperature. It is intended to be improved by the method according to the invention comprising compressing.

第1の工程段階で木質材料ボードの上面および底面を洗浄することによって、貯蔵中にまたは前の生産段階中に木質材料ボードの当該の箇所に堆積した埃または他の汚れを確実に除去する。このことは、付着される非常に薄い樹脂層が、非常に均一に上面に付着され、かつ、これらの層に凹凸または内包物が生じないようにするためには、重要である。   Cleaning the top and bottom surfaces of the wood material board in the first process step ensures that any dust or other dirt that accumulates at that location on the wood material board during storage or during the previous production stage is removed. This is important in order for the very thin resin layers to be deposited to adhere to the top surface very uniformly and to prevent the formation of irregularities or inclusions in these layers.

第1の上方の樹脂層にあるコランダム粒子によって、この層の耐摩耗性が増大される。このことは、特にフロアパネルとしての使用の際には、最重要である。その目的は、フロアパネルが晒されている既述の負荷に耐えることができるようにするためである。この場合、コランダムは、例えば、異なった粒度の通常のシラン化されたコランダムからなる混合物として存在し、樹脂に容易に添加されることができる。木質材料ボードの底面に、第1の下方の樹脂層が付着される。このことによって、第1の下方の樹脂層によって木質材料ボードに作用する引っ張り力が釣り合わされる。第1の下方の樹脂層は、特に着色されていてもよい。2つの樹脂層には、添加剤、例えば、硬化剤、濡れ剤または剥離剤が添加されていてもよい。続いて、第1の上方の樹脂層および第1の下方の樹脂層が乾燥される。その目的は、次の樹脂層のきれいな付着を保証するためである。乾燥は、例えば熱風によってなされる。樹脂が乾燥され、メラミン樹脂の化学的な架橋結合反応が停止される。この場合、塗料から水分が除去され、塗料は、約3%ないし6%の残留含水率に調整される。付着された残りの樹脂層も、その都度の乾燥の最中に、この残留含水率へもたらされる。   The corundum particles in the first upper resin layer increase the wear resistance of this layer. This is especially important when used as a floor panel. The purpose is to enable the floor panel to withstand the loads described above. In this case, the corundum exists, for example, as a mixture of normal silanized corundum of different particle sizes and can be easily added to the resin. A first lower resin layer is attached to the bottom surface of the wood material board. As a result, the tensile force acting on the wood material board is balanced by the first lower resin layer. The first lower resin layer may be particularly colored. An additive such as a curing agent, a wetting agent, or a release agent may be added to the two resin layers. Subsequently, the first upper resin layer and the first lower resin layer are dried. The purpose is to ensure clean adhesion of the next resin layer. Drying is performed by hot air, for example. The resin is dried and the chemical cross-linking reaction of the melamine resin is stopped. In this case, moisture is removed from the paint and the paint is adjusted to a residual moisture content of about 3% to 6%. The remaining resin layer deposited is also brought to this residual moisture content during each drying.

第2の上方の樹脂層にあるセルロースは、市販の繊維の形態で存在する。これらの繊維を、同様に、付着される樹脂層に添加することができる。第3の上方の樹脂層に入れられたガラスは、市販の微小ガラス球として存在する。微小ガラス球も容易に貯蔵されることができ、付着される樹脂層に入れられることができる。木質材料ボードの底面に付着された樹脂層は、着色されていてもよい。すべての樹脂層に、硬化剤、濡れ剤または剥離剤のような添加剤を添加することができる。   The cellulose in the second upper resin layer is present in the form of commercially available fibers. These fibers can likewise be added to the deposited resin layer. The glass placed in the third upper resin layer exists as a commercially available micro glass sphere. Small glass spheres can also be easily stored and placed in the attached resin layer. The resin layer attached to the bottom surface of the wood material board may be colored. Additives such as curing agents, wetting agents or release agents can be added to all resin layers.

3%ないし6%の残留含水率の乾燥によって、付着される樹脂層の架橋結合工程が中断される。圧力および温度の影響下での最終的な圧縮の最中に、樹脂層が再度溶け、架橋結合工程が継続する。このことによって、個々の樹脂層を、単独でのみならず互いに架橋結合させ、かつかくして圧縮して、大きなラミネートを形成することが保証される。通常の短サイクルプレスは、例えば30ないし60kg/cmの圧力で、約165℃の木質材料ボードの温度で、かつ6ないし12秒の圧縮時間で作業する。この場合、付着されたメラミン樹脂層は、装飾を内包しつつ、架橋結合される。パターン形成された圧縮プレートが使用されるとき、装飾に加えて、樹脂層にパターンがエンボス加工される。パターンが、装飾と著しく同一に形成されていてもよい。この場合、レジスタのエンボス加工のパターンについて記述される。 Drying with a residual moisture content of 3% to 6% interrupts the process of crosslinking the deposited resin layer. During the final compression under the influence of pressure and temperature, the resin layer melts again and the crosslinking process continues. This ensures that the individual resin layers are cross-linked together as well as alone and thus compressed to form a large laminate. A typical short cycle press works, for example, at a pressure of 30-60 kg / cm 2 , at a temperature of wood material board of about 165 ° C., and with a compression time of 6-12 seconds. In this case, the attached melamine resin layer is cross-linked while containing the decoration. When a patterned compression plate is used, the pattern is embossed in the resin layer in addition to the decoration. The pattern may be formed significantly identical to the decoration. In this case, a register embossing pattern is described.

第3の上方の樹脂層が、20%のガラス粒子の割合を含むことは好ましい。第2の上方の樹脂層に関して、約5%のセルロースが好都合であることが明らかになった。第1の上方の樹脂層は、特に20%のコランダム粒子を含む。   It is preferred that the third upper resin layer contains a proportion of 20% glass particles. With respect to the second upper resin layer, it has been found that about 5% cellulose is advantageous. The first upper resin layer contains in particular 20% corundum particles.

上方の樹脂層および下方の樹脂層を、20ないし50g/mの量で塗布することは好都合である。上面および底面に夫々付着されたメラミン樹脂層が同量で塗布されることによって、付着された層によって乾燥中に生じる複数の引張り力が互いに相殺されることが、同時に保証される。従って、木質材料ボードの底面に付着された対向層(Gegenzug)は、多層構造の点でおよび層の各々の厚さの点で、上面に付着された層順序に正確に対応している。20ないし50g/mの、このわずかな塗布量によって、同時に保証されるのは、特に木質材料ボードの底面に、たるみが生じないことである。 It is convenient to apply the upper resin layer and the lower resin layer in an amount of 20 to 50 g / m 2 . By applying the same amount of the melamine resin layer adhered to the top surface and the bottom surface respectively, it is simultaneously ensured that the tensile forces generated during drying by the deposited layer cancel each other. Thus, the opposing layer (Gegenzug) attached to the bottom surface of the wood material board corresponds exactly to the layer sequence attached to the top surface in terms of the multilayer structure and in terms of the thickness of each of the layers. This small application amount of 20 to 50 g / m 2 guarantees at the same time that no sagging occurs, in particular on the bottom of the wooden board.

上方の樹脂層および下方の樹脂層は、60%の合成樹脂溶液を含むことができる。   The upper resin layer and the lower resin layer can contain a 60% synthetic resin solution.

仕上げ加工される木質材料ボードの装飾の下方には、プライマーおよび下塗りが塗布されていてもよい。装飾は、この下塗りにプリントされ、カバーで被覆された。この代わりに、装飾が、貼り合わされた装飾用紙層の形で、木質材料ボードに付着されていてもよい。   A primer and a primer may be applied below the decoration of the wood material board to be finished. The decoration was printed on this primer and covered with a cover. Alternatively, the decoration may be attached to the wood material board in the form of a laminated decorative paper layer.

木質材料ボードを仕上げ加工するための装置であって、木質材料ボードの少なくとも1つの上面および/または少なくとも1つの底面は、装飾を有し、本発明では、(a)第1の両面塗布装置と、
(b)この第1の両面塗布装置の加工方向後方に設けられた第1の乾燥装置と、
(c)この第1の乾燥装置の加工方向後方に設けられた第2の両面塗布装置と、
(d)この第2の両面塗布装置の加工方向後方に設けられた第2の乾燥装置と、
(e)この第2の乾燥装置の加工方向後方に設けられた少なくとも1つの第3の面塗布装置と、
(f)少なくとも1つの第3の両面塗布装置の加工方向に後方に設けられた少なくとも1つの第3の乾燥装置と、
(g)短サイクルプレスと、を具備し、
各々の両面塗布装置は、樹脂層を木質材料ボードの上面に塗布するための上方の塗布装置と、樹脂層を木質材料ボードの底面に塗布するための下方の塗布装置とを有し、各々の上方の塗布装置および各々の下方の塗布装置は、夫々、1つの混合容器を有し、この混合容器の中で、その都度付着される樹脂は、少なくとも1つの添加剤と混合可能である。
An apparatus for finishing a wood material board, wherein at least one upper surface and / or at least one bottom surface of the wood material board has a decoration, and in the present invention, (a) a first double-side coating device and ,
(B) a first drying device provided at the rear in the processing direction of the first double-side coating device;
(C) a second double-side coating device provided behind the first drying device in the processing direction;
(D) a second drying device provided at the rear in the processing direction of the second double-side coating device;
(E) at least one third surface coating device provided on the rear side in the processing direction of the second drying device;
(F) at least one third drying device provided rearward in the processing direction of at least one third double-side coating device;
(G) comprising a short cycle press,
Each double-side coating device has an upper coating device for coating the resin layer on the top surface of the wooden material board, and a lower coating device for coating the resin layer on the bottom surface of the wooden material board. The upper applicator and each lower applicator each have one mixing container in which the resin deposited each time can be mixed with at least one additive.

装飾を備えた、仕上げ加工される木質材料ボードが、このような装置へ入れられる。少なくとも3つの両面塗布装置では、木質材料ボードの上面および底面が、同時に、樹脂層で被覆される。このことは、生産時間を短縮し、従って、製造コストを下げる。両面塗布装置に後置された乾燥装置には、たった今被覆された木質材料ボードが、所望の残留含水率に、例えば熱風によって乾燥される。かような両面塗布装置によって、夫々に第1の樹脂層の付着が迅速に可能となり、付着される樹脂層の架橋結合工程は、早期に中断される。樹脂層を乾燥させるための、被覆された木質材料ボードの中間貯蔵、または、他側を被覆するための、木質材料ボードの転向は、もはや不要である。   A wood material board to be finished with decoration is placed in such a device. In at least three double-side coating devices, the top and bottom surfaces of the wood material board are simultaneously coated with a resin layer. This shortens production time and thus reduces manufacturing costs. In the drying device after the double-sided coating device, the wood material board just coated is dried to the desired residual moisture content, for example by hot air. With such a double-side coating apparatus, the first resin layer can be quickly adhered to each other, and the cross-linking step of the adhered resin layer is interrupted early. Intermediate storage of the coated wood material board for drying the resin layer or turning of the wood material board for coating the other side is no longer necessary.

各々の上方の塗布装置および各々の下方の塗布装置が、1つの混合容器を有し、この混合容器の中で、その都度付着される樹脂は、望ましい添加剤と混合可能であることによって、種々の製品要求の間で、例えば、所望の耐磨耗クラスの間で、特に迅速にあれこれ調整を行なうことが可能である。多量の異なった樹脂・添加剤・混合物の、時間のかかる変更または貯蔵が、省略される。このことによって、保持される材料の量のみならず、設備の空間所要量も著しく減少される。同時に、種々の製品特性、例えば表面平滑性、耐酸性または耐摩耗性の適合が、即座にかつ簡単になされることができる。更に、高反応性の樹脂混合物の使用も可能である。何故ならば、被覆された木質材料ボードの中間貯蔵がもはや必要でなく、連続的な加工がなされるからである。このことによって、短サイクルプレスのサイクル時間も著しく短縮される。このことによって、再度、製造コストが下げられる。   Each upper applicator and each lower applicator has a single mixing container in which the resin that is deposited each time can be mixed with the desired additives, so that It is possible to make this adjustment particularly quickly between different product requirements, for example between the desired wear resistance classes. Time-consuming modification or storage of large amounts of different resins, additives, and mixtures is eliminated. This significantly reduces not only the amount of material retained, but also the space requirement of the equipment. At the same time, the adaptation of various product properties such as surface smoothness, acid resistance or wear resistance can be made quickly and easily. Furthermore, it is possible to use a highly reactive resin mixture. This is because intermediate storage of the coated wood material board is no longer necessary and is continuously processed. This significantly shortens the cycle time of the short cycle press. This again reduces the manufacturing cost.

本発明に係わる装置が、複数の貯蔵容器を有する貯蔵マガジンと、複数の供給ラインとを具備することは好ましい。これらの貯蔵容器の中で、付着される樹脂および添加剤は、夫々別々に、貯蔵可能であり、供給ラインは、貯蔵容器から混合物容器へ延びている。このことによって、樹脂および添加剤は、別々に、混合容器に運ばれ、そこではじめて、混合されて、塗布される所望の樹脂層を形成する。   The device according to the invention preferably comprises a storage magazine having a plurality of storage containers and a plurality of supply lines. In these storage containers, the resin and additives to be deposited can be stored separately, and the supply line extends from the storage container to the mixture container. This allows the resin and additive to be separately transported to the mixing container where they are first mixed to form the desired resin layer to be applied.

装置は、特に、供給ラインを通って混合容器に運ばれる樹脂および添加剤の量を制御するために設置されている制御装置を有することが可能である。従って、種々の製品特性および塗布量または添加剤の自動的な適合が可能である。   The device can in particular have a control device installed to control the amount of resin and additives that are carried through the supply line to the mixing vessel. Thus, automatic adaptation of various product properties and application amounts or additives is possible.

この場合、各々の上方の塗布装置および各々の下方の塗布装置は、塗布圧延機構であってもよい。このことによって、一定のおよび細かく調整可能な層厚が保証される。更に、かようにして、付着される層が非常に均一に付着される。   In this case, each upper coating device and each lower coating device may be a coating rolling mechanism. This ensures a constant and finely adjustable layer thickness. Furthermore, in this way the deposited layer is deposited very uniformly.

混合容器の中味を各々の上方の塗布装置および下方の塗布装置へ送り込むために、ぜん動ポンプが設けられていてもよい。このことによって、装置の寿命は、隔膜ポンプが使用される場合と比較して、最大20倍増大する。更に、ぜん動ポンプのチューブを、必要な場合に、急速交換システムによって、簡単かつ急速に交換することができる。このことによって、メンテナンス時間および修理時間を著しく減じることができる。   A peristaltic pump may be provided to feed the contents of the mixing vessel to each upper applicator and lower applicator. This increases the lifetime of the device by up to 20 times compared to when a diaphragm pump is used. In addition, the peristaltic pump tubing can be easily and quickly replaced, if necessary, by a rapid replacement system. This can significantly reduce maintenance and repair time.

各々の両面塗布装置の手前には、木質材料ボードのための少なくとも1つの押さえ手段が設けられていることができることは好ましい。このことによって、必要な場合には、木質材料ボードの、生産中に生じる変形が、除去され、被覆される木質材料ボードが、各々の両面塗布装置に正確にかつ再現可能に供給されることができる。   It is preferable that at least one holding means for the wood material board can be provided in front of each double-side coating device. This eliminates, if necessary, the deformation of the wood material board that occurs during production, so that the wood material board to be coated is accurately and reproducibly supplied to each double-sided coating device. it can.

装置の内部で木質材料ボードを搬送するために、尖形継目板コンベヤチェーンの形態をとる尖形バーコンベアが用いられる。尖形バーコンベア自体は、丈夫かつ信頼性が高くて、被覆した木質材料ボードの上面の品質を保証する。尖形継目板を、洗浄ブラシによって、自動的に洗浄することができる。   A pointed bar conveyor in the form of a pointed seam conveyor belt is used to transport the wood material board inside the apparatus. The pointed bar conveyor itself is sturdy and reliable, ensuring the quality of the top surface of the coated wood material board. The pointed seam plate can be automatically cleaned with a cleaning brush.

両面塗布装置からコンベヤチェーンへのまたはその逆への木質材料ボードの引渡しは、この場合、滑車によってなされる。両面塗布装置または乾燥装置に入るや否や、更に、滑車の形態の既述の押さえ手段が用いられる。   The delivery of the wood material board from the double-sided applicator to the conveyor chain or vice versa is in this case made by a pulley. As soon as it enters the double-sided coating device or the drying device, the aforementioned pressing means in the form of a pulley is used.

更に、木質材料ボードを仕上げ加工するための装置は、全体の層厚および機能性添加剤の数および役割を高めるために用いる他の両面塗布装置を有することができる。従って、上位の使用クラスに指定されることができる製品も製造される。同様なことは、3つより多い樹脂層を、被覆される木質材料ボードの上面および底面に付着させることができる、本発明に係わる方法に、当てはまる。   In addition, the apparatus for finishing the wood material board can have other double-side coating apparatuses used to increase the overall layer thickness and the number and role of functional additives. Accordingly, a product that can be designated as a higher usage class is also produced. The same applies to the method according to the invention in which more than three resin layers can be applied to the top and bottom surfaces of the wood material board to be coated.

ここに記載した装置を制御するためには、電気的な、特にコンピュータ支援の制御が用いられるとき、付着される樹脂層の高い再現可能性を達成することが可能である。何故ならば、樹脂および添加剤の混合割合のみならず、例えば乾燥装置および短サイクルプレスの温度制御手段も、自動的に制御されることができる。このことによって、かくて製造された製品の高い品質標準が達成可能である。更に、例えば、種々の下塗り層および装飾層の付着によって、生じることができる、被覆される木質材料ボードの種々の湾曲状態を、上面および/または底面における塗布量の制御によって、自動的に埋め合わせることができる。   In order to control the device described here, it is possible to achieve a high reproducibility of the deposited resin layer when electrical, in particular computer-aided control is used. This is because not only the mixing ratio of the resin and the additive, but also the temperature control means of, for example, a drying apparatus and a short cycle press can be automatically controlled. This makes it possible to achieve a high quality standard for the products thus produced. In addition, the various curved states of the coated wood material board that can occur, for example, by the application of various undercoat and decorative layers, are automatically compensated by controlling the application amount on the top and / or bottom surface. Can do.
